49UP20180806 - ph
Weighted mean crs offset of 0.006 with 2 out of 9 offsets being either negtaive
or very close to 0. All others show an offset of at least 0.005. A pattern can
not be detected here. The carbon interconsistency check indicates a good fit
(offset of -0.0026). Maintain.

49UP20180806 - cfc113
Very spready saturation levels varying between 5 - 20% oversaturation mostly. No
pattern visible which is in contrast to CFC_11 and CFC_12. Also note the
extremly high residuals to the expected CFC_11 curve... I am not sure if an
adjustment alone improves these data… -777?

49UP20180806 - cfc11
All surface concentrations are oversaturated. This is surpsising as most
locations usually show undersaturations as the norm. Also the fit with CFC_12 is
not good. Especially when compared to CFC_12 the actual trend towards lower
concentrations with higher station numbers (further south) is present, too, but
simply at least 10% offset (high) at all stations. Adjust downward to match
CFC_12 better.

49UP20180806
10% oversaturation for CFC_11 and CFC_12 seems to be in line with other
summertime cruises in the northern Pacific

49UP20180806 - cfc113
Very spready saturation levels varying between 5 - 20% oversaturation mostly. No
pattern visible which is in contrast to CFC_11 and CFC_12. Also note the
extremly high residuals to the expected CFC_11 curve... I am not sure if an
adjustment alone improves these data… -777?

49UP20180806 - cfc11
All surface concentrations are oversaturated. This is surpsising as most
locations usually show undersaturations as the norm. Also the fit with CFC_12 is
not good. Especially when compared to CFC_12 the actual trend towards lower
concentrations with higher station numbers (further south) is present, too, but
simply at least 10% offset (high) at all stations. Adjust downward to match
CFC_12 better.

49UP20180806 - ph
Weighted mean crs offset of 0.006 with 2 out of 9 offsets being either negtaive
or very close to 0. All others show an offset of at least 0.005. A pattern can
not be detected here. The carbon interconsistency check indicates a good fit
(offset of -0.0026). Maintain.
